ValidationError：MongooseError.ValidationError的用户验证失败

Question

我正在尝试使用mongoDb创建一个带有护照本地身份验证的简单node.js应用程序并将其表达为框架，但我遇到了问题

每当我尝试使用注册表单将数据提交到数据库中时，在单击提交后，它立即显示在节点终端中：

这是我的用户架构的样子：

    var mongoose = require('mongoose');
var bcrypt   = require('bcrypt-nodejs');

// define the schema for our user model
var userSchema = mongoose.Schema({

    local            : {
        name    : String,
        username     : String,
        mobile       : Number,
        email        : String,
        gender       : String,
        password     : String

    }
});

// methods ======================
// generating a hash
userSchema.methods.generateHash = function(password) {
    return bcrypt.hashSync(password, bcrypt.genSaltSync(8), null);
};

// checking if password is valid
userSchema.methods.validPassword = function(password) {
    return bcrypt.compareSync(password, this.local.password);
};

// create the model for users and expose it to our app
module.exports = mongoose.model('User', userSchema);

和我的路由器文件：

 // process the signup form
    app.post('/signup', passport.authenticate('local-signup', {
        successRedirect : '/profile', // redirect to the secure profile section
        failureRedirect : '/signup', // redirect back to the signup page if there is an error
        failureFlash : true // allow flash messages
    }));

注册逻辑的护照配置：

    passport.use('local-signup', new LocalStrategy({

    nameField     : 'name',    
    usernameField : 'username',
    mobileField   : 'mobile',
    emailField    : 'email',
    genderField   : 'gender',
    passwordField : 'password',
    passReqToCallback : true // allows us to pass back the entire request to the callback
},
function(req, name, username, mobile, email, gender, password, done) {

    // asynchronous
    // User.findOne wont fire unless data is sent back
    process.nextTick(function() {

    // find a user whose email is the same as the forms email
    // we are checking to see if the user trying to login already exists
    User.findOne({ 'local.email' :  email }, function(err, user) {
        // if there are any errors, return the error
        if (err)
            return done(err);


        // check to see if theres already a user with that email
        if (user) {
            return done(null, false, req.flash('signupMessage', 'That email is already taken.'));
        } else {

            // if there is no user with that email
            // create the user
            var newUser            = new User();

            // set the user's local credentials
            newUser.local.name     = name;
            newUser.local.username = username;
            newUser.local.mobile   = mobile;
            newUser.local.email    = email;
            newUser.local.gender   = gender;
            newUser.local.password = newUser.generateHash(password);

            // save the user
            newUser.save(function(err) {
                if (err)
                    throw err;

                return done(null, newUser);
            });
        }

    });

    });

}));

我是node.js以及mongoDb的新手，请帮帮我 谢谢

原因：此错误背后的原因是要存储在db中的无效类型。和移动设备一样是数字类型但是如果你传递的值不能转换为数字那么它会产生同样的错误。

的console.log（NEWUSER）;在保存用户并检查您在移动字段中传递的值之前，可转换为Number，因为其数据类型是架构中的数字。

如果手机是＆＃34;＆＃34;或未定义或null，即不可转换为数字，那么它将无法工作。如果该值不存在，请从对象中删除此键。不要传递undefined，null或＆＃34;＆＃34;或字符串（不能转换为数字）。
